still

A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol.

    Right, I've got the hang of the DuoTech coupled to the NEST but, sadly, I have a problem with an EcoBlue 33 now. I've wired it as in the diagram attached but I can't seem to get it to fire on the CH. Fine on the DHW. The NEST is working fine, as far as I can tell. It's got 12V from the T1 T2...

    Hi, Can anyone give me an idea what is causing this problem? CH and DHW both start normally, but after about 20 seconds after the burner has ignited it makes this load noise. Sounds a bit like a airplane flying over! Then the temp on the gauge very quickly rises and the burner shuts...

    To cut a long story short, I started reading the the WRAS Water Regs book again: G16.1 d states that a G1/2 size valve (do they mean a 1/2" valve as opposed to, say, a 3/4" valve?) must be 'constructed so that the water shut-off level may be altered [...] without bending the float lever.' So...
